Abstract：

Learning chemistry manipulative technique requires not only mechanical imitation and skillful operation, but also skill concepts to effect learning transfer and hence to solve the chemistry experimental problems encountered. This study uses content analysis (structural task analysis, process-concept analysis, and hierarchical concept mapping), CLD theory and step-by-step learning model to analyze sublimation manipulative technique. The structural task analysis identifies the sequential and part-whole relationships of sublimation technique. Process- con-cept analysis identifies the critical attributes and variable attributes of sublimation manipulative technique. Hierarchical concept mapping of sublimation indentifies how this technique is relat-ed to prerequisite skills. The mental operation in action of four successive learning attainment levels for sublimation manipulative technique are identified.
